IMPRQVEMENT IN CONDENSERS.

y Specification forming part of Letters Patent 216,254, atedllebruaryV,1865.

Z'o @ZZ whom it may concern:- l

Waters.; -and IF-do hereby declare that the' following-is a full and exact description of the same, reference beinginade to the accom- I panying drawings, and to the letters of .ref-

erence vmarked thereon, in Which.-

Figure 1 is a vertical longitudinal section taken throughwthe` line marked .5c fr in. Fig. 12,

and Fig.` 2 is a transverse sectioiftaken,`

vthrough the line markeda bin l". 'My invention' relates to 4an improvement uponthe potablewater'condenser secured to me'by Letters Patent ofthe lUnited-States under date'ot'Apil 22, 1862; and it consists in taking the supply of .cooling vaterthrough the tubes of thev lower (or. cooling) section ot' the lcondenser and returning it through therupper (or condensing) series of tubes," y whereby the watercondensed and' collectedV in the lower section is m'ore thoroughly cooled than it' would be if the cooling water entered A,both the condensing and" cooling tubes at the same time, and'wherehy the purpose of the condensation of 'the steam in the apparatus is more thoroughly effected with the'same supply of cooling water than itvwould be by the flow of'cooling Water throughv the condensing-tubes alone.l This arrangement alsoeffects the object oibrin'ging thevcooling-water delivery-pipe, the .cooling-water receivingpipetlie.entrance-pipe for the steam-to be. condensed, andthe pipe for carrying oil theI condensed'water at'the'same end of theap" paratus, whereby the Whole series of pipes can be got at for repair or examination more readily thanvif theywerel placed at opposite endsof the apparatus.A l V- f The ,case ot" the condenser, its divisionplates and tubes, and its drip-plate and dripreservoir are constructed and. arranged the same as those shown and described inthe Letters latent above named, excepting that the tubes in the cooling-section A are increased in number suiiieiently to receive and pass through the-supply of cooling .Water received through the nozzle 13,- and. that the number of tubes in the condensingsection (.l

'that'the division-plate G is placed 'in the head space ofthe apparatus (as shown) to the first action of the cooling water received through the nozzle B shall be through the coolingtubes A, in-order that' the condensed Water falling into the cooling-section shall bev more thoroughly cooled than it would be if the said plate were not used. The cooling-water is received through the nozzle B, and, after passing through thecooling-tubes A, is vreturned back through the condensing-tubes C, and is passed ott' through the nozzle D. The steam tobevcondensed is received into, the apparatus through the nozzle E and passes-across and between the tubes in section C, as shown fvallinginto the' cooling-section through apertures made at proper intervals in'the dripplate F, and being taken oli` through the nozzle-G. 1 The nozzle H is used to take olf voir can be cooled down to such'degree as to render it lit for use when delivered fromy the nozzle G, lsothat the condensed water does not require to stand to be cooled after y being made. i

' The arrangement-of the receiving and de- Alivery"cooling-Water pipes and the steam and condensed water delivery pipes at the same end of the apparatus is of great advantage, as it brings allthe said pipes at one end ofthe apparatus, Where they can readily be got at'for repairor examination, and enables the apparatus to be erected 'in positions (particularly on shipboard) where it Awould be impossible or iinpracticable to erect it if the apparatus'.v v

.What I Aclaim as my invention, and desire -to secure .by Letters Patent, is

g l. The combination ofthe division-plate U l with the section ot cooling-tubes A, .as and v' for the purpose set forth.

l 2. The combination ofthe division-plate C,

l with thetubesheet and cover to the end o is decreased in the same proportion, and also divide that'spacc into.. two sections, so that by the darts in Fig. 1, the condensed Water 4the incondensable vapor. By this arrangef ment the condensed Water in the drip-reserthe pipes named were at the opposite ends ot*- the case (as shown) for the purpose of divdplate C', placed at the. same end of the aping the space between the said tubesheet and cover into two sections, as set forth.

3. The arrangement of the cooling-,Water reeeivingvnozzle B, thecooling--Water delivery-nozzle D, the steam-nozzle E, the conmused-waterr nozzle G, and the division-- paratus, as shown', and yfor thefpufposes setz fort-h. r
